In this paper, a three-dimensional turbulent study was carried out on Manzanares (Spain) plant to study the effects of collector inclination angle (θ). Different ranges of θ (30–0°) with more than 15 models were considered for the analysis. An optimized θ has been proposed based on the estimated parameters such as air velocity, pressure drop, absorber and air temperatures, power developed, collector efficiency, and overall efficiency (η_coll and η_o). At θ = 6°, an increment of 9.16% in theoretical power (P_th) and a 10.68% increase in air velocity were observed at the chimney base (CB) compared to the horizontal collector plant. Any further increase in θ (greater than 7°) resulted in recirculation of air particles within the collector canopy, leading to obstruction of flow. Any value of θ lesser than 6° resulted in a drop in the major outputs such as P_th, η_coll, and η_o. Eventually, θ = 6° has been proposed as optimized inclination. The dynamic pressure difference was maximum at a chimney height of 2.5 m from CB; therefore, this was the preferred location for turbine fitment. The results were compared with the experimental data of the Manzanares plant, and a very favorable agreement was noticed.

在本文中，对 Manzanares（西班牙）工厂进行了三维湍流研究，以研究集热器倾角 ( θ ) 的影响。分析时考虑了超过 15 个模型的不同范围的θ（30-0°）。已根据空气速度、压降、吸收器和空气温度、产生的功率、收集器效率和整体效率（η _coll和η _o）等估计参数提出了优化的θ。在θ  = 6° 时，理论功率增加 9.16% ( P _th) 并且与水平收集器设备相比，在烟囱底部 (CB) 观察到的空气速度增加了 10.68%。θ 的任何进一步增加（大于 7°）都会导致收集器顶篷内的空气颗粒再循环，从而导致流动受阻。任何小于 6°的θ值都会导致主要输出（例如P _th、η _coll和η _{o ）}的下降。最终，θ = 6° 已被建议为优化倾角。烟囱高度为 2.5 m 时，动压差最大；因此，这是安装涡轮机的首选位置。将结果与 Manzanares 工厂的实验数据进行了比较，发现了非常好的一致性。
